.. LEAD-PENCIL.

Toall whom it ma/g i cohcern:

, Be it known that L1 WILLIAM B; MoKnsr, a subject of the-King of Great Britain, and

a resident of Elizabeth, in the countyof Union and, State of-New Jersey, have invented a newlgand useful Improvementin Lead-Pencils, of which the'following is a full, clear,gandiexact description.

' The purpose of the invention is to provide a lead pencil-with a removable-magazine clip for the sticks of lead, which clip'can be manufactured and soldlindependeiitly "of the.

holder, and can be readily'placed inposition in aholder, secured therein, and be conveniently and expeditiouslyr'emoved therefrom when empty for the introduction of a loaded iclip. a

It is a further purpose of the invention to I so constructt-he magazine clip that a num-.

ber of leads ofdifferent sizes and 'difierent degrees of hardness, if desired, canbe placed in exterior" pockets from which they can be readily removed, and to provide the clip with an opening extendingtherefrom to re-.

ceive a conducting tubefconstitutinga po'rtion of the holder, said tube being'adapted to support and guide the lead in use to the point of the holder. 7

It is also a urpose of the invention to rovidea simp e and positive feed for the ead in use and means whereby said feedis I operated by a single movement of an. ex-

teriorl'y located sliding-plate.

.Another' purpose of the invention is to.

provide a means for-causingthelead inserted in the conducting tube to feed outwardthe' fragments of the formerly inserted-lead re maining in the holder,'should said fragments have passed the regular feeding device.

The invention consists in the ,novelcon structlon and-combmatlon of the several parts as will. be. hereinafter fully setforth and pointed out inthe claims.- 1

mechanism is made; Fig. 5 is a perspective view of the" completed box orcasing, and j-Fig. 6 is a perspective view of-the expanse 'bletube for the lead.

encil is Y The body of the holder of the made in twomain sections,.a barre section A, and a tip or forward section B. The barrel section A' is closed at its rearend by a cover 10 and this cover is provided with a central inwardly extending pin 11 for a purpose to be hereinafter described-.. The opposite or forward end of the barrel section A is closed, as is shown at 12 in Fig. 2-, with the exception of a centrally threaded opening 13,

and at the forward end of the closed end 12 of theilsaid barrel, an interiorly threaded cover 14 is formed, adapted to be screwed upon the exteriorlythreaded reduced rear end of the lid section B of the holder, as is alsoshownin Fig. 2. The said tip or forward section B ofthe holder is provlded with a well 16 formedtherein, referably rectangu- 13.1 in shape, and this we 1 is open at a side of o Q I the SELHl't-lp section, as 1s also shown in Fig.

2. A bore 17 extends through the rear end portion of the tip section B connecting with thesaid well, and a'second and correspond- 7 ing bore 18 extends .fromthe said well 16 out throu h the point I) ofthe said tip section B,

both. ores 17 and "18 being in alinement. Adjacent the well 16 an ex ansible extension tube 19 is inserted in the ore 18 of the ti section, and this tube" has a head 20 thatis countersunk in the forward wall of the said Well, as is also shown in Fig. 2, and this extension tube is ada ted to hold the lead in use against forwar movement when pressure is exerted upon lts outer or pomted end.

I The barrel section A is adapted tocontain a magazine .cli

barrel, and the said magazine cli is constructed, as is shown in Fig. 3, preferably of asingle piece of metal bent to t'u'bular form, and provided with exteriorlongitudina'l cor C" which is {practically the length of the c ambered portion ofthe said rugati'ons forming a series of longitudinal ex? terior pockets 21, each pocket being adapted toreceive a stick of lead- 22. "{The sticks of lead should be the;full.'length ofxthe clip,

since thenare' held in'pos'ition. on the-clip by portions of. t e clip,- and the ends oftliesticks of lead rendering the latter, readily removable. The forward cap 23 is providedwith a central opening 24 of sufficient size to admit means ofca s 23 that "are fitted over theend the passage of a tube 25,.and the rear cap v W AVAILABLE 25, which conducting tube is open at both ends, and at its forward end is screwed into a threaded o ening 13 of the forward closed end 12 of the said barrel, as is illustrated in Fig. 2, since the conducting tube is a fixture, while the magazine clip is removable and is 'ada ted to be substituted byanother when the ead is exhausted therefrom. It

placed in position. on the barrel A the pin 11 carried by the cover extends into the said and in connection with the lead in use a feed device is employed that is located in the well 16 and should a fragment of lead remain in the tip section of the holder occupying such a position that it could not be engaged by the said feed device or mechanism, then when the new stick of lead is introduced ir itothe conducting tube 25 and the cover 1-0 is placed in position, the introduced stick of.

lead will be forced by the pin 11 of the cover sufficiently far forward to be engaged .by-the;

said feed mechanism, and thus as the inscrt' ed stick of lead is fed forward or outward it feeds the said fragment in the same direct ion..

The well 16 is provided with a box l), and this box, or casing as it may be called, is made preferably from the blank shown in Fig. 4, but it may be otherwise constructed. This blank is substantially rectangular in general formation, and at the two opposing sides is provided with registering recesses 26 and a central opening 27, and at a side at right angles to that containing the recess 26 a tongue 28 is projected from the body of the blank, and at the same side an angular slot 29 is made in the body of the blank, which slot 29 is removed from the said tongue 28, and adjacent the said tongue 28, likewise at the same side of the blank astepped recess 30 is made, and ad j aceht the angular recess 29 the blank is provided with an aperture 31, and the tongue 28 has a corresponding aperture 32 formed therein. At the side of the blank tom a, showrf in Fig. 2, which lies upon the bottom of the well 16 and is secured to the lid. section B by means of a screw 35, or its Carried down 1 equivalent. Thus opposing side members a and a are provided, as is illustrated 1n Fig. 5, that bear against the sides of the well and then the lip 28 is bent so as to have bearing against both sides constituting one end of the box or casing, and the lip 28 is similarly bent to constitute the opposing end portion, while. the material adjacent the recess 2.!) is then bent inward to engage with the side a of the box, forming a third and intern'iediate cross piece a". The cross pieces 28, 23, and u are in longitudinal alinement, as are likewise the apertures produced therein, designated as v 32, 33, and31. The upper or open portion of may be here stated that when the cover 10 is .being uridcr'each side of the box.

A feed i-neclianism is located within the -well, or rather within the box or casing l).

This'mechanism' is as follows: A sliding linger'plate 36 mounted on the outer face of the lid section B of the holder covering the 90 mouth.ofjthe-f and a guide'=lug'37 s n 'the'under faceof the linger 'plate-36'into tlic. saidjwellnear the outer or forwar'i l eni'lof said" plate, [and a correspomlingttripffinger:38 isc'arried'i'lown to the well 'l'ronrth'e under face of the said plate adjacent ts opposite end, the said lug-37 and trip linger 33 havingapertures therein. A pin 3!) is passed through the apertures in the upper cross pieces of the box or casing, being securedthereto, and the said pin 3!), which is in the nature of a shaft, isv loosely passed through the lug 37 and the trip linger 33 of the sliding linger plate. 36, as is shown in Fig. .2. A spring 40 is coiled around the shaft or spindle 39, having hearing at one end against the upper cross member a of the box or casing, and at its opposite end against a sleeve 41 mounted to slide on the said s indle 3!), which sleeve is in engagement wit 1 the forward side of the trip finger 38 thus when the plate 36 is pushed forward, or toward the point of the holder, the spring 40 is placed under compression, and when the finger or sliding plate is released the spring returns to its normal position, and it is obvious that the trip finger 38 moves with the said plate. ad acent that at which the recesses 29 and 30 An ejector 42 is mounted about centrally between the sides of the box or casing l), being secured centrally on the pin, which pin mounted to slide in. the lower sections of the stepped recesses 30, as is shown in Fig. 2. This ejector has a head at each of its ends extending downward, but the head at the forward end extengls'likewise upward so as to form a projection at such point, and the said ejector 1s held withadownward and rearward inclination bythe trip finger 38 when the sl dmg plate 1s 1n normal ositionfiandiis held wlth a downward "and 'orward inclination' when the. sliding plate is mjma, toward the 1 in a hone pocket having media -lemma;

This is done b the action- .of the trip finger 38 which slides along the u per edgeof the ejector and bears thereon a5- went one or the other of its ends according v 'to the position of the sliding plate 36. .The leadas 'inv use is provided with a series of notches 44, and these'notches are located a r di'stancea art 'correspondingto the distance between't e heads of the ejector. When the sliding plateis in its normal osition the rear head rests in one of the said notches, but as the sliding plate'is moved outward the trip finger presses the outer or forward end of the bringing the forward head into the notch '44;
